One day close to Tanabata, the members of Procellarum are at one of Japan's scariest haunted houses at an amusement park for filming for a television program. On the day of filming, Fuduki Kai, one of the members of Procellarum, had a certain dream. It was a dream that was filled with memories of Tanabata――. As soon as filming began, Kai, who was paired up with Rui, saw something and disappeared, chasing after that something.

Two years ago, when the plan was launched by "Tsukipo shop in Harajuku 2018" ——. As a concept in the shop, there was a "Fairy Tail Collection" that dressed in costumes designed with the image of a "nursery story". The fairy tale to be taken up is that you can decide freely in each unit, and Yayoi Spring, whose production blood is noisy, offered to suggest a story of Gravi. However, a major fairy tale was quickly decided by another unit, and a good idea came out. Looking at him who was worried, I invited him to a specialty store for picture books. What did spring meet there...?

Procera's waterless tears born to a musician's family, and his brother's waterless Ryo's brother had an English-speaking education that became a pianist from an early age. Tears were quickly recognized for their talents and were touted with geniuses, but his brother Rika had a past that gave up on the piano (music) path after being overwhelmed by his brother's talent. Because of that, the two, who had been estranged for a long time, however, now solved the rut and returned to their close brothers. One day, in tears, an offer of piano recitals that doubles as a full festival advertisement. Procera members and tears thinking about the production of recitals visit the work site to hear the opinions of the sea that were out. It happens to be a university hospital where my brother Ryo works...

"Six Gravity (Six Gravity/commonly known as Gravi)" and "Procellarum" (Proceralum/commonly known as Procera) belonging to Tsukino Entertainment Production (commonly known as Tsukipo). Their next goal of expanding their place as a signboard unit in Tsuki is the joint live "Full Moon Festival 2020 (commonly known as Full Moon Festival 2020/)"! Gravi's teacher, along with Kisaragi's love, was to take a comment from a member who was willing to live for this live. With the theme of "new themselves", a comment video shooting tour produced by two people who keep up with location search and schedule adjustments will be fulfilled and will end successfully...! ?

For the shooting of a promotional video, Gravi and Procella are at a resort island! From enjoying marine sports to a beach volleyball showdown, both groups are having their fill of the island and summer! With the shooting going as planned, all that's left now is free time... when a tragic crime has occurred! Without so much as a single lead on who committed the crime, Koi, claiming the title "the Great Detective Koikku", has set out to solve this crime! Will Koikku discover the one and only truth!?

From that point on, I was in charge of the design of clothes by a female magazine plan, and I was in charge of Kisaragi in Gravi. The design theme is "Clothes that make you smile". Although the finished design was well received from the surroundings, I think that love itself lacks a deciding hand somewhere, and love decides to design again. With the words of her younger sister Ai in mind, a new design concept is decided, and with her partner Shiwasu Kakeru and Procellarum's fashion specialist Hazuki Haru joining the team, what will be the "clothes that will make you smile" that Koi will design as she aims to complete the project?

Theater version "Tsukino Empire". The epic "world of things" story was an important work for the god of Procera, Iku, who grew himself. "I'm hungry..." Iku, who woke up late at night, sees the "Tsukino Empire" package in the shared room. It's the cup yakisoba that looks back at the video and picks it up. Yoyang, who also made me hungry there, and the cooking manager's long night appeared again... I want to imitate it, full of olivine recipes! Enjoy the charm of both the cool guys in the military uniform and the hungry off. "Today is Iitero..."

At the scene of a shooting, Procera members were praised for their growth buds by the photographers who knew when they made their debut. While unexpectedly remembering and nostalgic for the time being, Bungo Sea felt comfortable for the first time in a stable unit, but without any problems. "I haven't ventured recently..." Due to the chubby and spilled murmuring, the other members worry about the sea, but the opponent, Hayato Frost Moon, is absent... At that time, the sea met a mysterious cat.

Gravi and Procella's, who are at a resort island for the shooting of a promotional video, are now involved in more trouble! Because of a sudden storm, any means of obtaining essential utilities have been cut off! With a strange, large creature littering the island, they have decided to investigate the island, with Hajime and Shun as the leaders. In such terrible weather, Hajime's group, who have left the forest route, has found at the end of their hardships a......!?

I was looking through my script and I and felt that my character was somewhat similar to you back then. I...... don't have many pictures of back then, after all." Yoru, who borrowed You's junior high pictures for the sake of being able to get into his character for a drama, ended up finding another nostalgic item, and looked back to their time as junior high students――. Childhood friends You and Yoru had completely different personalities, yet despite that, got along very well and spend a lot of time with each other. However, as they grew older, the people they hung-out with changed, and the two grew distant. During those days, Yoru, who thought everything had changed, learned about the You's unwavering feelings.......

Aoi and Koi, as part of a variety show, have to wake-up ambush the members of Gravi and Procella. Even if it's part of work, Aoi, who is not used to doing such ambushes to his friends, and Koi, who's all for it. And so these two quietly sneak into the other members' rooms and give their feedback! Will they be able to succeed in their wake-up ambush? Will the veiled, secret private lives of these idols, whose fame has been on a steady rise, be revealed...!?

As the day of Gravi and Procella's joint concert approaches, the spirits of all members are on the rise! Though amidst all of it, only Gravi's leader, Hajime, has glum look on him. While his unit members seem to get worried of him, who is very busy with not only his duty as the unit leader, but also with solo jobs, it seems those aren't the only reason behind his low spirits... The one that Haru, his partner, and Kai, a fellow senior member, chose to become someone that Hajime can consult with is ―― obviously, none other than this person. The elegant yet lazy leader of Procella, the White Demon Lord: Shun.

One day, Rui caught sight of the "Tsukiusa." mascots (a familiar sight at the "Tsukino Dorms") walking. These "Tsukiusa."s were apparently looking for something important, so Rui decided to give them a helping hand. Actually, these "Tsukiusa."s are also the members of the female idol units "Fluna" and "Seleas", who also belong to the same company. These girls, who originally were from the Moon Society, for some reason became "Tsukiusa."! To be able to return to their original forms, Rui and the girls, embark on a strange and charming journey!

Hajime has suggested that during the joint live between Gravi and Procella, all 12 members sing a new song everyone can enjoy. Even though all the members and the managers agree the idea, they would need to get Tsukino Talent Production's President Tsukino Mikoto's approval to be able to turn Hajime's idea into a reality, as well as have him write the song, as he has worked on all their units songs up to that point. But it looks like asking the President such a thing is difficult, as he is currently carrying heavy pressure do to work...? Will Gravi and Procella be able to show the fans who've waiting for live the new bonds, the new song they've formed...!?

Procera's Yoyo Eisuki and Gravi's Kisaragi have decided to appear as guests in the "High School Dance Colosseum" dance contest for high school students. The two will form a special team with Okui Wings of SolidS (Solids) as an office selection, Kensuke Hachigashi of Growth (Gross), and ROCK DOWN (Lockdown) nominal Luka, and Yang will be the team leader. It was supposed to be appointed. One day, when the special session was on track, members of the special team were selected by ZIX's rival office, Sun Promotion and Entertainment (commonly known as Samplo), including ZIX's Makoto Suzaku. I know that the team will participate. It is a de facto office selection showdown. Aiming for a dance like ourselves while bringing together members who are full of character as leaders. The Yang challenge has begun!
